XT2052 1A Compatible With the USB Interface, Linear Battery Management Chip ■ General Description The XT2052 is a constant- current / constant- voltage charger circuit for single cell lithium-ion batteries. The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications. XT2052 requires minimal external components, and meet the USB bus specification, is very suitable for portable applications in the field. Thermal modulation circuit can control the internal chip temperature in a safe range when the device power dissipation be relatively large or the ambient temperature be higher.
